Adding Legend, need help to add to my script..

MatthewLopez — Fri, 02 Dec 2011 01:16:51 GMT

I am having difficulties adding a legend script to my original basemap script. Need guidance or any recommendations, so that I may be able to add (where can I add within the original script) the legend script to my original basemap script? Hope I am saying this correct...

I need to the script within this URL, which is my legend (please see below):
https://gis.sanantonio.gov/ArcGIS/rest/services/BikeFacilities/MapServer/legend

into my original basemap script (please see below):

Hi Matt,

There are a couple of issues with your code:
-only add your bike facilities layer once
-add an HTML element, e.g. a <div>, with an id that matches what you specify in the legend constructor
-modify your layer to have a name or specify one manually

Here's a modified version of the code you posted:
